Table tennis is a sport where two players hit a ball back and forth to each other, with a racket on a table, in a manner similar to tennis. The rules are slightly different, but the concept is essentially the same. Table tennis is an Olympic sport, "ping-pong" is the recreational version of the same sport. Spin, speed and strategy play an important part in competitive table tennis matches. The speed of the ball can vary from slow spinny serves to fast smashes that travel as fast as 110 km/h.[citation needed]

The playing surface is a 9 ft5 ft30 in high (2.7 m1.5 m.762 m) hard rectangular table with the surface usually colored green, dark blue, or black. A 6 inch (15.2 cm) tall net divides the table in half (much like a tennis court) and is strung to extend 6 inches (15.2 cm) beyond the table on each side.

It is often difficult for beginners to learn to use the correct footwork. At the beginning, you can get away with poor footwork since it is not the most important part of the game. But as you get better having good footwork becomes more and more important, until it is an essential component of the game in advanced play.

Play is fast and demands possibly the quickest reactions of any sport. A skilled player can impart spin to the ball which makes its bounce difficult to predict or return with confidence. Spin combined with speed makes table tennis an exciting sport to play as well as to watch. The difference between Olympic level play and the average home recreational player is tremendous. Often a proper foundation of table tennis skills is required to understand how competitive players can do what seems impossible to the untrained eye.

Keep your crouching position as much as you can while playing - this helps keep your center of gravity low, and will help you move around the court more smoothly. Standing up straight will raise your center of gravity, lock your knees and impair your ability to balance and move quickly.
